Adaptive Filtered-epsilon Inverse Compensation of a Nonlinear System

Abstract

An adaptive inverse control approach is put forward to control a kind of typical nonlinear system with hysteresis characteristic. An inverse of the hysteresis operator is proposed and the inverse nonlinear model is built. Then the structure of filtered- ^ε LMS algorithm is simplified and a new adaptive inverse control system is built to reduce the nonlinearity and achieve accurate tracking control. Simulation results illustrate the proposed scheme's effectiveness.
